INDIRECT LIGHTING FIXTURE Filed Jan. 4, 1935 INVENTOR Leroy C Doane ATTORNEY Patented Jan. 5, 1937 UNITED srarss PATENT OFFICE INDIRECT LIGHTING FIXTURE of Connecticut Application January 4, 1935, Serial No. 322

2 Claims.

The present invention relates to indirect lighting fixtures and is more particularly directed toward indirect lighting fixtures of the type provided with an opaque reflector and a translucent 5 bottom adapted to be illuminated and preferably arranged to transmit light to the outer surface of the reflector for illuminating the same.

The present invention contemplates an improved arrangement for securing an opaque reflector, usually made of sheet metal, and the glass bottom member together. According to the present invention these parts are designed so as to be received within a channel-shaped ring.

Under certain lighting. conditions, it is: desirable to build up the indirect component and reduce the amount of light allowed'to fall on the translucent bottom member, and according to the present invention the fixture is provided with a baiiie preferably made removable and located so as to intercept downwardly emitted direct light. This balile is so disposed so as to permit a small amount of scattered light to pass between the balile and the glass member to dimly illuminate the same.

The accompanying drawing shows, for pur-- poses of illustrating the present invention, an embodiment in which it may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same. In the drawing:

Fig. 1 is a vertical sectional view through the fixture parts in elevation;

Fig. 2 is a horizontal sectional view taken on the line 22 of'Figure 1; and

Fig. 3 is a fragmentary view showing a detail.

The lamp socket It supports a pendant lamp bulb II and is surrounded by a socket cover E2. The socket cover supports straps l3 secured at their lower ends in eyes It carried by an upwardly and outwardly flaring opaque reflector it. The inner edge of this reflector is indicated at I6, and is downwardly flanged as indicated at ll.

The glass closure member I8 has an opening in the top of such a size as to receive the flange ll. A split channel-shaped ring it fits about the reflector and closure member as indicated in Figures 1 and 3 so as to hold the two parts. together. To facilitate collapsing this ring, it is provided with a small knob 29.

The ring I9 carries a number of upwardly extending spring fingers 2i preferably corrugated as indicated. These fingers are adapted to re-' ceive a downwardly dished reflector or baflie 22 and support it spaced above the bottom of the glass closure.

This baffle acts to screen off direct light which would otherwise fall on the glass closure and to reflect this light to reinforce the indirect illumination. Some of the light from the lamp strikes the reflector It at low enough angles to be scattered underneath the baffle 22. Such rays are indicated at 23. The baffle may be readily removed when an increased portion of directlight is desired.

It is apparent that, within the scope of the invention, modifications and different arrangements may be made other than that herein disclosed, and the present disclosure is illustrative merely, the invention comprehending all variations thereof.

What is claimed is:

l. A lighting fixture comprising a pendant lamp bulb, an open bottomed, upwardly and outwardly flaring reflector about the bulb, a diffusing glass closure having its upper edge adjacent the bottom of the reflector, a channel shaped ring embracing the reflector and closure, a plurality of spring fingers carried by the ring, and a removable bafiie carried by the fingers for preventing direct light from falling onto the closure.

2. In a lighting fixture, a pendant light source, an open-bottomed, annular, outwardly and upwardly flaring opaque reflector, a diffusing bottom closure of larger diameter than the opening in the bottom of the reflector, means for securing the closure and reflector together with the upper, inner edge of the closure secured adjacent the lower inner edge of the reflector whereby downward light is diffusely transmitted downwardly by the closure for direct lighting, and upwardly forilluminating the outside of the reflectors, and an opaque bafile removably carried by said securing means and disposed between the light source and closure to intercept direct light, the baiiie being spaced from the closure and. the lower edge of: the reflector to reflect downwardly light reflected to it by the lower part of the reflector and scatter such reflected light into the diffuser, whereby the indirect lighting effect of the fixture may be increased at the expense of the direct lighting without rendering the closure and outer reflector surface non-luminous.
